Add Helm chart for SlimFaas

[Copilot]

Adds a production-ready Helm chart to simplify SlimFaas installation and upgrades on Kubernetes, based on the existing demo manifests.

Chart structure (helm/slimfaas/)

• Chart.yaml — chart metadata
• values.yaml — defaults matching the demo deployment (3 replicas, resource limits, probe config, Prometheus annotations)
• templates/serviceaccount.yaml — ServiceAccount + two Role/RoleBinding pairs (deployment/statefulset manager, endpoints viewer); both toggleable via rbac.create / serviceAccount.create
• templates/statefulset.yaml — StatefulSet with dual PVCs (/database 2Gi, /backup 1Gi), configurable replicas, resources, probes, and env vars
• templates/service.yaml — headless ClusterIP: None service with publishNotReadyAddresses: true for SlimData consensus
• templates/configmap.yaml — optional ConfigMap for SlimFaas__JobsConfiguration; only rendered when jobsConfiguration is set
• templates/ingress.yaml — optional Ingress (disabled by default), supports ingressClassName and TLS
• templates/NOTES.txt — post-install access instructions

Quick install

helm install slimfaas ./helm/slimfaas --namespace slimfaas --create-namespace

Notable defaults

Value	Default
replicaCount	3
image.repository	axaguildev/slimfaas
defaultVisibility	Public
persistence.database.size	2Gi
persistence.backup.size	1Gi
ingress.enabled	false
rbac.create	true
